This Arduino UNO clone worked well out of the box. I have tested it on the Arduino IDE 1.0.5 and 1.6.0 without any problems. However, Arduino IDE 1.6.1 did not recognize the board well, and I could not upload a sketch. Pros: almost half the price of an original Arduino, with all the features.

However, Arduino IDE 1.6.1 did not recognize the board well, and I could not upload a sketch. Pros: almost half the price of an original Arduino, with all the features. The included cable is pretty short, but seems to be well built. Holes next to female pins are quite useful to attach it to a breadboard. Cons: it is an SMD version, so you cannot change the processor, if you burn it. In addition to that, it has several pads to solder pins (pins are attached in a separate bag :D), but there is no datasheet to figure out why to solder them.Read more

Had to solder a 100 uF capacitor between ground and 3.3 Volt line in order to be able to use nRF24L01+ modules (too much electrical noise)Read more

The products bought on-site DX Deal Extreme are excellent, shipping is very fast as well, with the accompaniment of purchase. When I needed support was promptly answered. Continue purchasing products from this website because I am very satisfied with the service.

I would like to open my curtains automatically, depending on light input during day or night. My attention was drawn by this board. It seemed to have all functionallity I needed. First I downloaded from the Arduino site the text editor/compiler and some sample programs to learn how to use this board. It was not too difficult, so I ordered the board. It is so cheap, you can't burn your fingers, when it should not do what I wanted. Also, from DealExtream I bought two relais for motor control, two line hunting sensors for position detection and a light sensor. After some programming, testing, reprogramming, all started to work. Most difficult is the making of the mechanical construction for accomodating the sensors and the motor to open/close the curtains. Now everythings works and it works stable. No hick-ups from the micro controller. Amazing product for such a low price which included free and fast shipping by DealExtreme.Read more

Pros: *Good quality, almost like the original one. *Same pin layout and microchips as the original UNO R3. *Because of the above, can use with the Arduino IDE just as if it was the original one. *Costs just ~3 dollars more than buying just one ATmega328 with Arduino bootloader already *Actually...Pros: *Good quality, almost like the original one. *Same pin layout and microchips as the original UNO R3. *Because of the above, can use with the Arduino IDE just as if it was the original one. *Costs just ~3 dollars more than buying just one ATmega328 with Arduino bootloader already installed.
Cons: *Actually it could be even lower price. *The USB cable could be longer.
Other thoughts:
The cons are not really important ones, but make the difference between 4-stars and 5-stars.Read more

+ Bright RX,TX Leds
+ Works with the Arduino IDE (duh) Cons :
- None that i can think of.Read more
